Users of the git revision control system discuss tips, configuration and tools for using it effectively.

Major free software projects including Linux, Samba,
and X are relying on git, and software collaboration
sites including GitHub, Gitorious, and Sourceforge
support it. But more than any other revision control
system, git has spawned a bewildering array of hacks,
hooks, and alternate workflows.

This panel discussion will bring together a variety of
git users--who use it for tasks such as open-source
and in-house software projects, a public web site,
system administration, a wiki, and small-scale
individual projects. As panel moderator, I'll
coordinate the panelists to discuss deploying
and managing software with git, how to implement
policy and workflow (including how to use git as a
centralized revision control system), and the ultimate
git hook: a git-backed wiki.

The panel should inform Linux users who just want to
follow the latest version of their favorite software
or track down a bug with "git bisect," help webmasters
and sysadmins who want something more than rsync,
and of course give software developers some ideas
about productive ways to work together.

In this new talk by Jono Bacon, Ubuntu Community Manager and author of The Art of Community by O'Reilly, he explores the evolution of Open Source, Free Culture and social media and explores the mechanics behind the revolution that is changing the way people learn, create and interact with each other.

Using his trademark British humor, pumped full of stories, anecdotes and thought-provoking conclusions, Bacon deconstructs the web of innovations that started with one man getting angry with a printer and have led to a world-changing movement, complete with the opportunities, risks, internal struggles and growth that has come along for the ride. The Engine Of Revolution provides a intriguing yet entertaining assessment of the story so far; the ideal start to a weekend of diverse and wide ranging content at SCALE.

Hardware Load Balancers can run into the thousands, sometimes tens of thousands, of dollars, but did you know you have a Load Balancer right in your very own Linux box? LVS (Linux Virtual Server) is a free, easy way to Load Balance across web-servers or any other mass-scalable read-only services on your network, while taking up a very small footprint. In this lecture, you will learn how to enable and configure the Load Balancer that has been hiding inside your 2.6 kernel all this time...

We examine the use of XMPP to manage hundreds of servers in various environments.

Cloud infrastructures have provided a great deal of power and versatility, but come at a cost of management overhead. In many cases, a node in a cloud infrastructure has no guarantee of being there at any given moment, has an indeterminable spin up time, and has no way of determining apriori where it will be. These make it hard to coordinate work across the nodes.

The typical approach for these setups is to provide an HTTP based registrar. While that works in many cases, the lack of bidirectional communication introduces a bit of ambiguity. What is happening between checkins? Does a node need to unregister itself? What happens when a node goes down?

Botnet shepherds have long been dealing with similar problems as cloud shepherds are dealing with now. A botnet node can go down at any time, there is no way to determine when a node will come into the botnet, and botnet nodes come from all over the place. Currently, the primary mechanism that botnet shepherds use to control their networks is over IRC channels. While the primary appeals have been the low barrier to entry, the always on messaging infrastructure, and the inability to lock down the channel, this approach provides an efficient way to coordinate activity in an environment with the above issue with little overhead.

Given the similarities between managing a botnet herd and managing a cloud herd, why not use the same management mechanisms that botnets use for more above the board purposes? How well do instant messaging infrastructures work for cloud infrastructures?

In this talk, we examine how we can use the botnet herding techniques to manage a large host of servers in a couple of scenarios. We will look at using XMPP as a transport mechanism for a traditional hosting environment as well as a cloud environment.

In this talk Kyle Rankin will cover basic concepts for a forensics investigation using Sleuthkit and Autopsy. The talk will feature a demo with a real compromised system.

In this talk Kyle Rankin will provide an introduction to performing forensics analysis on Linux machines using the popular Sleuthkit tools with their easy-to-use Autopsy web-based front-end. The talk will cover initial installation and configuration of Sleuthkit and Autopsy, basic concepts and considerations for a forensics investigation, and at the end there will be a demo with a real, compromised Linux image.

While some developers are happy working alone on a project for their own use, many others would rather build a community of developers, users, content creators, translators, and so on. In order for that to happen, the word needs to get out -- people need to know about the project and what it
is trying to accomplish. There are lots of ways to do that, but many projects make it unnecessarily hard for interested folks to find out what they are up to. Because of that, good work languishes, opportunities for cross-pollination between projects are lost, and free software is not as
good as it could be.

This talk will give some guidelines and ideas for projects that want to do a better job of presenting what they do to the greater free software
world. We'll cover things like interfacing with the press, using blogs and mailing lists, web site organization, and more. Participants should leave
with a much better idea of how to make a bigger splash with their projects.
